In F2803x, the phase delay between EPWMs (from SPRUGE9E) is defined in
Figure 7. Time-Base Counter Synchronization Scheme 1 (page 27).
In this figure, the synchronization order of ePWM1, ePWM2 and ePWM3 is very clear, but for ePWM4 to ePWM7, it only uses ePWMx to express.
I consider it has 3 possibilities:
1. synchronization order can only be ePWM1, ePWM2, ePWM3, ePWM4, ePWM5, ePWM6 and ePWM7.
2. Only 4 ePWM can be synchronized, that is, after ePWM3, only one ePWM can be synchronized, and it can be any one ePWM from ePWM4 to ePWM7.
3. After ePWM3, ePWM4 to ePWM7 can be synchronized in any order.
Any one let me know the exact way about F2803x synchronization between ePWMs?
